cd /path/to/processing-0154 && ./processing

(In reply to comment #1)
well, if it is really necessary to first change into the processing directory,
then the wrapper script should handle that.

which however leads to another problem: if i'm changing the working directory,
all dialogs for opening and saving files are starting in that dir, causing
grave pain to the user who tries starts processing from some project dir and
has to click back to what is supposed to be his working dir every time he
wants to use a file open/save dialog.

i had a same problem, and i created another shell script in the same folder
for executing the main script :D
lame solution but it works...

That's what this line should be doing:

APPDIR="$(dirname -- "${0}")"

Though that was contributed by someone else who claimed it worked. If
that's not the case, please let us know.
